01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or foil, and set a wire rack on top.
02 - Pat chicken wings dry with paper towels. Place in a large bowl and toss with olive oil, salt, pepper, smoked paprika, garlic powder, onion powder, cayenne pepper, and chili powder until evenly coated.
03 - Arrange wings on the prepared rack in a single layer. Bake for 40 minutes, turning once halfway through, until crispy and golden brown.
04 - While wings bake, whisk together mayonnaise, sour cream, buttermilk, parsley, chives, dill, garlic powder, onion powder, salt, pepper, and lemon juice in a medium bowl until smooth. Refrigerate until serving.
05 - Transfer hot wings to a serving platter. Serve immediately with chilled ranch dressing on the side.
